As demand for basic metals grows, engineers and scientists are looking for new ways to extract these elements from ores. “The easy stuff has already been found and processed. One of the main challenges of mining and minerals processing companies is now the economical processing of low-grade ores”, says Steve Rogers, managing director of the Parker Center for Integrated Metallurgy Solutions...

Sulfur dioxide emissions from metals smelters and other process plants are typically treated by converting the SO2 to sulfuric acid, but this may not be convenient, because of the shipping cost for plants located far from an acid market. WorleyParsons (Monrovia, Calif.; www.worleyparsons.com) offers a solution to this problem with a process that converts SO2 to elemental sulfur, which is easier and safer...

Researchers from the University of Cantabria (Santander, Spain; www.unican.es) have developed a process for incorporating Waelz slag into ceramic clay construction bricks, offering an alternative for disposal of the industrial byproduct. The engineers replaced between 20 and 30% of clay with slag, and found that the inclusion at that level did not have any significant detrimental effect on the physical...

In the emerging and ever-expanding areas of bioprocessing, where maintaining hygienic designs and practices is of paramount importance, and semiconductor manufacturing, which has its own stringent purity requirements, there is a need to standardize the essential codes and standards that are available. The goal is to consistently achieve process systems that meet the highly refined cleanliness and...

Metso (Helsinki, Finland; www.metso.com) is supplying a 140-MWth biogasification plant to Vaskiluodon Voima Oy in Vaasa, Finland. When it starts up in December 2012, the €40-million gasification plant, which will be located next to the existing 565-MW coal-fired power plant, will convert biomass (mainly forest residues) into a so-called biogas that can be combusted with coal. The gasification facility...

A novel nickel-manganese-gallium alloy, introduced by Goodfellow Corp. (Oakdale, Pa.; www.goodfellowusa.com), elongates in a magnetic field, allowing the conversion of magnetic field energy into kinetic energy. The material offers an alternative to conventional actuators, and could find other uses in energy harvesting systems, breaker switches, sensors and others. Grown as a single crystal using a modified...

Scaleup is set for two technologies that facilitate the capture of carbon dioxide from fluegas by substituting oxygen for combustion air. Oxycombustion, as it is called, results in a much smaller fluegas stream, containing up to 90% CO2; part of that is recycled to dilute the O2 and control the combustion temperature. The O2 is entrained in the CO2 stream for injection into the furnace. The companies...

One of the most important measurements in the chemical process industries (CPI) is rate of flow. Flowrates can be important to measure, and in fact can be critical to measure, throughout a process — from dosing components into a reactor to material transfers in-between process steps, to discharging products at the end. Flow metering technologies fall into four classifications: velocity, inferential...

There was a time, not long ago, when most groups responsible for industrial control systems (ICS) in the chemical process industries (CPI) were not much worried about security. They had their firewalls in place and their remote access servers, and overall that worked for them. Rarely, a virus would sneak in and usually do little damage. The affected computers would need to be shut down and cleaned out, but...
